Webbmoment of inertia, in physics, quantitative measure of the rotational inertia of a body—i.e., the opposition that the body exhibits to having its speed of rotation about an axis altered by the application of a torque (turning force). The axis may be internal or external and may or may not be fixed. The moment of inertia (I), however, is always specified with respect to … WebbA section is taken at an intermediate location C along the pipe’s axis, Fig. 5–12 b . The only unknown at the section is the internal torque T . We require \sum{M_y}=0; \quad\quad 80N(0.3m)+80N(0.2m)-T=0 . T=40N·m. Section Property.
